//5V connect to DC 5V power supply
//GND ??ground
//====================================== LCD screen data line wiring ==== =====================================//
//The default data bus type of this module is 8-bit parallel mode
//8-bit mode wiring: 8-bit mode 9341 module is connected to the high 8-bit bus, namely:
//LCD_D0 corresponds to the single-chip microcomputer PB8
//LCD_D1 corresponds to the single-chip microcomputer PB9
//LCD_D2 corresponds to the single-chip microcomputer PB10
//LCD_D3 corresponds to the single-chip microcomputer PB11
//LCD_D4 corresponds to the single-chip microcomputer PB12
//LCD_D5 corresponds to the single-chip microcomputer PB13
//The LCD screen LCD_D6 corresponds to the microcontroller PB14
//LCD_D7 corresponds to single-chip microcomputer PB15
//====================================== LCD screen control line wiring ==== =====================================//
//LCD_RST connects to PC5 //reset signal
//LCD_CS connect to PC9 //chip select signal
//LCD_RS connects to PC8 //register/data selection signal
//LCD_WR connect to PC7 //write signal
//LCD_RD connect to PC6 //read signal
//======================================== touch screen touch wire ==== =====================================//
//This module's touch test needs to be connected to an external XPT2046 touch sampling chip, so this program does not perform touch testing.
//If you don¡¯t use touch or the module itself does not have touch, you don¡¯t need to connect
